Just got this and started fixing it up. It was filthy so I cleaned it all. Took power transistors out so they would'nt get soaked by cleaning. Checked the Pt's and all were good. Found a ballast resistor with broken lead fixed that new three prong. DE ox all boards. Replaced 10k pot. Fired it up and popped the fuse. I did not fire it up before doing all this because of the shape the power cord was in. Kinda scratching my head now. Ant help will be apreciated. Thanks.
